Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511630, here are decompositions:

3 + 511627 = 511630
47 + 511583 = 511630
71 + 511559 = 511630
89 + 511541 = 511630
107 + 511523 = 511630
167 + 511463 = 511630
173 + 511457 = 511630
191 + 511439 = 511630

Showing the first eight; more decompositions exist.
